I'm just going to suggest a bunch of them, didn't give any requirements so just listing ones I've watched recently that I liked.

They're going to mostly be romantic comedies, because that's what I've been into lately.

Kimi ni Todoke - Sawako Kuronuma has had a difficult time fitting in. Some say it's her jet black hair, others say it's her hushed manner of speaking, while still others claim it is due to her name's similarity to Sadako, a character from a popular Japanese horror series. On her first day of high school, Sawako meets the one boy who treats her like a normal girl-Shota Kazehaya. Through his selfless aid, Sawako slowly learns to come out of her shell and even begins to make friends for the first time in her life. However, with a new social life come social pressures. Rumors begin to circulate about her, her friends, and even the kindhearted Kazehaya. As she grows into her new identity, Sawako must learn to deal with such pressures as well as start to understand the unfamiliar feelings inside of her, especially in regards to the boy who made her new start possible.

(The main character is really funny, and she's extremely likable because she is so innocent and desperate to be liked by her friends. It's sometimes frustrating because of misunderstandings that her naivety produce, but it's a really great show.)

Say I Love You - Tachibana Mei has had no boyfriend and couldn't even make friends. One day she injures Kurosawa Yamato, the most popular boy in school, and for some reason Yamato takes interest in her.

(This one is really similar to Kimi ni Todoke, expect the main character is a little tsundere instead of naive and clueless.)

Love, Chunibyo & Other Delusions - Yuta Togashi has a problem. He used to be a "chunibyo," one of the thousands of Japanese students so desperate to stand out that they've literally convinced themselves that they have secret knowledge and hidden powers. But now that he's starting high school, he's determined to put aside his delusions and face life head on. The trouble is Rikka Takanashi, his upstairs neighbor, is just a little bit delusional herself. And she knows all about his past indiscretions.

(Easily one of my favorites, the first half of the season will have you laughing your ass off, the second half will have you crying like a baby.)

Bakemonogatari -“Bakemonogatari” (translated “Ghost Story”) was written by Nisioisin, one of the most popular writers in Japan, and the series consists of 5 different stories. Thanks to Meme Oshino, Koyomi Araragi, a high school student, is able to remain a human after coming across a female vampire.. However, since the incident, Koyomi seems to meet girls who have an apparition-related issue. Hitagi Senjyogahara doesn’t weigh anything, Suruga Kanbaru’s right arm becomes like that of a monkey’s, and a young girl, Mayoi, cannot find her way home no matter how many times she tries. Koyomi, a Mr. Nice Guy, ends up helping each and every girl solve her problem with the help of Meme Oshino.

(This one is hard to explain. You'll just have to watch it to understand how awesome it is. The only thing I can compare it to is the feeling I got when watching Fight Club for the first time.)

Sword Art Online - In the near future, a Virtual Reality Massive Multiplayer Online Role-Playing Game (VRMMORPG) called Sword Art Online has been released where players control their avatars with their bodies using a piece of technology called: Nerve Gear. One day, players discover they cannot log out, as the game creator is holding them captive unless they reach the 100th floor of the game's tower and defeat the final boss. However, if they die in the game, they die in real life. Their struggle for survival starts now.

( This one is going to be controversial. The first half of the first season was really great, but they ended the main's plot conflict way too early, and the suspense of the death game ends abruptly. Some people can't forgive it for doing that, I was able to and still enjoyed it.)

There's a bunch of others I could recommend but it would turn into a novel.

Ahhh, I forgot Maid Sama . It's not on crunchyroll, but I definitely recommend it.
